Many of the players carried on their celebrating well into yesterday afternoon; Chiefs co-captain Liam Messam tweeted "I think the boys are still going haha" shortly after midday.
Hamilton hospitality identity John Lawrenson, who owns several bars with Chiefs members, said the players were "gearing up for a huge one" when he saw them after their win on Saturday.
"I think it is a well-deserved blowout because they have been very committed this year," he said.
"They have obviously focused on their title, got what they deserved and now they are celebrating."
Mr Lawrenson said thousands of fans descended on central Hamilton after the game and scenes in town were similar to those after All Black tests.
"It was a really good night and any incidents that there were were really just minor. It was one of the best crowds I have seen - these were people who were just out to have a good time."
Buoyed by consistent performances and better weather, the Chiefs enjoyed a surge in popularity and attendances at their home games were up more than 90 per cent on last year.
The franchise's chief executive, Gary Dawson, said he was overjoyed the team had finally achieved the one goal that had eluded them in their 17-year history.
"It is very difficult to achieve and s not many teams have done it ... so it's a huge achievement and it is testament to the coaches and the guys and the hard work they have put in over the past nine months.
"We are very, very proud of what the boys have done."
A Chiefs parade down Victoria St today at 12.30pm will culminate at Garden Place, where the team will receive the city's official congratulations.
"This is the city's way of saying thanks to the Chiefs, who've thrilled us with their play this season and capped it off with their first title, won on their home ground, said Hamilton Mayor Julie Hardaker.
The Chiefs' title win crowns a stellar year for sport in the Waikato after the successes of the Lake Karapiro-trained Olympic rowers, the ANZ Championship winners Waikato Bay of Plenty Magic and the Plunket Shield-winning Northern Districts Knights cricketers.
